Problems solved by technology
[0002] In the production process of construction, machinery manufacturing and other industries, a level is often used. The existing level usually uses the principle of a vial; this level can only measure whether it is level, and it cannot be determined for non-level surfaces. The specific inclination angle can only be roughly judged based on experience at that time, and it will be troublesome to measure again after adjustment
[0003] Patent No. ZL02259167.2, the six-bubble level discloses a level that can measure four slopes of four fixed angles 1 / 100, 2 / 100, 3 / 100, and 4 / 100, corresponding to an ordinary level. There has been some progress, but it can only measure the slope of four values, and it is still inconvenient to use

Embodiment Construction
[0019] The digital display level of the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments.
[0020] In the figure, the number 1 is the housing, the number 2 is the extension rod, the number 3 is the dial, the number 4 is the rotating shaft, and the number 5 is the reading window.
[0021] see figure 1 — Figure 4 , a digital display level, comprising a housing 1, an extension rod 2 is set on both sides of the housing 1, a round pie-shaped dial 3 is installed in the housing 1, and the upper and lower bottom surfaces and side surfaces of the dial 3 are They are all marked with scales. The center of the dial 3 is provided with a conical rotating shaft 4. The inner side of the housing 1 is fixed with a rotating sleeve. The two ends of the rotating shaft 4 are set in the rotating sleeve. The dial 3 can rotate with The shaft 4 rotates freely, and the dial 3 is provided with an overweight, and a circle o...

The invention discloses a digital-display type level ruler, which is simple in structure and can read out an inclined angle. The digital-display type level ruler comprises a shell, wherein the shell is internally provided with a dial; a rotating shaft is arranged at the center of the dial; two ends of the rotating shaft are arranged at the inner side of the shell; the dial can rotate along the rotating shaft; an inclined weight is arranged on the dial; a circle of scales are uniformly engraved on the dial; the scales at two ends of the diameter of the center of the inclined weight on the dial are 0 degree, and the scales at the two ends of the diameter, which is vertical to the diameter with the 0 degree, are 90 degrees; and the positions at the upper part of the shell, which correspond to the scales of the dial, are provided with reading windows which are provided with reading lines. The digital-display type level ruler disclosed by the invention has the advantages that the specific inclination angle can be measured, and convenience is provided for production and construction; since the reading windows are arranged, reading in the different directions on the reading windows can be realized according to the measurement need; and the digital-display type level ruler is convenient to use.
Description
technical field [0001] The invention relates to a measuring tool, in particular to a digital level. Background technique [0002] In the production process of construction, machinery manufacturing and other industries, a level is often used. The existing level usually uses the principle of a vial; this level can only measure whether it is level, and it cannot be determined for non-level surfaces. The specific inclination angle can only be roughly judged based on experience at that time, and it will be troublesome to measure again after adjustment. [0003] Patent No. ZL02259167.2, the six-bubble level discloses a level that can measure four slopes of four fixed angles 1 / 100, 2 / 100, 3 / 100, and 4 / 100, corresponding to an ordinary level. There has been some progress, but it can only measure the slope of four values, and it is still inconvenient to use. Contents of the invention [0004] The purpose of the present invention is to provide a digital level with simple structure...
